MAINTENANCE
Exhaust System
Check the exhaust system for wear or damage at approximately 2000
miles (3200 km). Always allow the engine and exhaust system to cool
completely before inspecting.
1. Open the hood and inspect the muffler and pipes for cracks or dam-
age.
2. Check for weak or missing retaining springs or damper/support
grommets.
3. Check for loose clamps on the pipe covers.
Drive Chain Tension
Check drive chain tension weekly and
before each long trip. To obtain correct
chain tension:
1. Rotate the driven clutch counter-
clockwise to move all chain slack to
the tensioner side. Lock the brake
lever lock, or have an assistant hold
the brake lever firmly.
2. Loosen the adjuster bolt jam nut (1).
3. Finger tighten the adjuster bolt (2)
until it can no longer be adjusted by
hand, then back off 1/4 turn.
4. Tighten the jam nut while holding
the adjuster bolt. Torque to 21 ft.
lbs. (28 Nm).
5. Release the brake lever lock.
WARNING
Hot exhaust system parts can cause serious burns. Allow adequate time for
the exhaust system to cool. Never perform this procedure with the engine
running.
